Fenno-Skan 1 HVDC connection capacity will be reduced

Fenno-Skan 1 cable voltage will be reduced with 20 % as a security measure until the cable failure investigation results are available at the end of May 2013. As a result of this the capacity of Fenno-Skan 1 will be limited to 450 MW and the total Fenno-Skan capacity to 1250 MW.

Fenno-Skan 1, the 550 megawatt HVDC connection between Finland and Sweden, tripped from the grid 12th February 2013 due to an internal cable failure. The cable was repaired 12th April 2013, but the investigation into the cause of the failure continues.
